Dispensing device for particulate material

Abstract

A particulate material dispensing assembly comprises a container for storing particulate material and includes an end cap device having a passageway for discharging the particulate material. The end cap device is disposed at a discharge end of the container and includes a removably mounted brush. The container includes a base section, a delivery section and a collapsible resilient coupling section connecting the base section to the delivery section.

       4. An assembly as defined in claim 1 wherein the end cap means includes a lid base member, brush means and a brush securing member,   the lid base member includes a recess having a shaped inner peripheral edge surface, and   the brush securing member has an outer peripheral edge surface having a structural configuration effective to slidably fit into the shaped inner peripheral edge surface of the recess for holding a brush means which is disposed between said inner peripheral edge surface and outer peripheral edge surface and extends outwardly from the end cap means.   
     
     
       5. An assembly as defined in claim 4 wherein the brush securing member has an outer lateral surface and includes projection means extending outwardly from the outer lateral surface by an amount effective to be grasped by the fingers of a user to insert and remove the brush securing member into and out of the recess of the lid base member.   
     
     
       6. An assembly as defined in claim 5 wherein the projection means includes an aperture registered with an open passageway defined by a first conical surface in the lid base member, and   the registered aperture is defined by a second conical surface coextensive with the first conical surface of the lid base member passageway.   
     
     
       7. An assembly as defined in claim 4 wherein the brush means includes a securing portion disposed between the shaped inner and outer peripheral edge surfaces to removably fix the brush means to the lid base member for brushing particulate material dispensed through the conically-shaped passageway upon pressing together the base section and delivery section to cause the coupling section to collapse thereby discharging particulate material from the container.   
     
     
       8. An assembly as defined in claim 7 wherein the shaped inner and outer peripheral edge surfaces each includes a striated surface configuration to fasten a continuous securing edge portion of the brush means in a zigzag path between the two peripheral edge surfaces.   
     
     
       9. An assembly as defined in claim 1 wherein the end cap means includes a brush fixing member having a plurality of holes through which brush bristles project outwardly from a first side of the fixing member and securing means fix the brush bristles to the other side of the fixing member.   
     
     
       10. A dispensing device for particulate material, said device comprising: a) a container having a dispensing end cap means and defining a chamber in which particulate material may be disposed for storage,   b) said container having a single longitudinal axis, a shell housing wall having an outer surface structural configuration formed along two shell housing sections secured on opposite sides of an elastically recoverable bellows portion, said outer surface structural configuration being effective to fit in a single fist of the user and the elastically recoverable bellows portion is peripherally located along the housing wall and in a plane that is disposed at an angle other than normal to the longitudinal axis,   c) said dispensing end cap means including passageway means adapted to allow particulate material stored in said chamber to be dispensed therethrough when exerting manual pressure to cause the bellows portion to collapse by an action of a single hand pumping within the user's fist.   
     
     
       11. A device as defined in claim 10 wherein the dispensing end cap means includes an end cap member removably mounted to the container.   
     
     
       12. A device as defined in claim 11 wherein the removable end cap member includes removably mounted brush means composed of a disposable material.   
     
     
       13. A device as defined in claim 10 wherein the end cap means includes brush means and an end cap cover means connected to the container,   said brush means being detachably mounted to the end cap cover means.   
     
     
       14. A device as defined in claim 13 wherein the end cap cover means includes an end cap member,   the container has an outer end opening defined by an annular container end wall and shoulder means projecting outwardly from the container end wall,   the end cap member has an annular wall member that slidingly pressure fits against the container end wall and is thereby effective to preclude the discharge of particulate material therebetween upon pumping the bellows portion.   
     
     
       15. A device as defined in claim 14 wherein the container end wall includes an outer end abutment surface and an annular shoulder projects toward the longitudinal axis of the container,   said outer end abutment surface is located in a plane disposed at an angle other than normal to the longitudinal axis.

A device as defined in claim 10 wherein the container shell housing wall is defined by a rigid shell housing having a rigid delivery shell section and a rigid base shell section, and   the bellows portion includes an annular collapsible coupling member connected at one side thereof to the rigid delivery shell section and at the other side thereof to the rigid base shell section.   
     
     
       17. A device as defined in claim 16 wherein the end cap means includes brush means having a securing portion for removably mounting the brush means to the container.   
     
     
       18. A device as defined in claim 10 wherein the plane of the bellows portion is disposed at an angle of about 60° from the horizontal and about 30° from the longitudinal axis.   
     
     
       19. An assembly for applying particulate material, said assembly comprising: a) a container defining a chamber for storing particulate powder material and including two rigid cooperating sections joined together by a third resilient deformable annular section,   b) said rigid and resilient sections defining an outer shell housing having an outer shell surface structural configuration effective to fit in a single hand of the user, said container including an upper lid having an opening whereby the powder may be expelled through said opening by exerting manual pressure along the outer shell surface with the user's single hand to push the two rigid cooperating sections toward the resilient section which partially collapses when performing an action of single hand pumping of the container to expel the powder by the pressure applied within the user's fist,   c) end upper cap means being disposed at a discharge end of the container and including a container lid having an upper face,   d) said upper end cap means including fastening means removably mounting separate brush means composed of disposable material,   e) said separate brush means being removably secured on the upper face of the container lid to allow fast replacement of a used brush means with another brush means.   
     
     
       20. An assembly as defined in claim 19 wherein the container consists essentially of a three piece shell housing including said two rigid sections joined together by said resilient section to form said outer shell surface having an outer periphery,   said resilient section extending along the entire outer periphery of the outer shell surface.
